NO. 3 OSBURN : EASTERN PACIFIC BRYOZOA—CYCLOSTOMATA 661
2. T. lobulata Hassall. Differs from T. lobulata Hincks in having
long oblique series of connate zooecia. (Hassall, 1841, pl. X, fig. 2).
I think Norman may well have been right (MS. note) in referring it
to T. serpens (T. liliacea Pallas).
3. T. lobulata ? Osburn. Resembles T. lobulata Hincks in its stout
zooecia with thick transversely striated walls, and in the arrangement
of the zooecia in the colony, separately or in small groups, but not in
connate series; and in the depressed ooecia. Differs in its less ramified
ovicell with the ooeciopore placed more or less symmetrically at the
center of the distal border of the ooecium closer to, and behind rather
than beside, a zooecial tube; in the small size of the ooeciostome and in
the absence of an out-turned rim to the ooeciostome." (The last item
must now be corrected as I have a complete ooeciostome with a slightly
out-turned rim. R.C.O.)
It is a pleasure to be able at last to solve the long-standing problem
of the position of the West Atlantic specimens of "T. lobulata," which
could not have been done without the careful analysis by Dr. Hastings,
to whom I gratefully dedicate the species.
The species is now known to be distributed on the Atlantic coast from
Mount Desert Island, Maine (Osburn, 1933:16); Gaspe (Canada),
Hincks Collection (Hastings, in litt., British Museum), and Greenland, "Valorous," 1875, Norman Collection, (Hastings, in litt., British
Museum). Now I am able to add the Bering Sea, and the species is
certainly high northern and possibly circumpolar in its distribution.
Type, AHF no. 117.
Type Locality, Nunivak Island, Bering Sea (a large island off the
west coast of Alaska, about 60°N, and 116° W) at 8 to 10 fms, on
shell, 4 colonies. Another specimen is marked merely "Behring Sea,"
on shell.

Platonea Canu and Bassler, 1920:759; 1929:548.
Reptotubigera d'Orbigny, 1853:751 (in part).

This genus has been accepted by the above authors to include narrow,
fasciculate species that are entirely adnate to the substratum, as described
by d'Orbigny. But d'Orbigny made no reference to the ovicell, the first
